v BRICKMAKINGr-MACHINE.

To all whom t may concern: i `Be it known thatI, DANIEL E. Rmenma citizen of the United States, and a'resident `of Columbus,` in the county Vof Franklin and State of oOhio, yhave invented certain new and useful Improvements in Brickmaking-Machines; `and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to `make and use the same.

. My invention relates to an improvement in brick making machines, and particularly to machines forthe manufacture of paving bricks having `projections on one or more faces for holding them apart so asto permit` the cement, grout or other filler commonly used for binding purposes, tobe readily poured or inserted between the bricks or blocks, and which also facilitate thelaying of said bricks by keeping them inalinement. `The object of the invention is to provide an attachment which may be'applied to the ordinary brickmaking machine for finishing the two faces of the clay bar as itleaves the. machine and` fory forming the projection on one face. c c l c VA furtherI object is to provide means whereby the weight and friction of the mov- `ing bar of clay actua-tes the finishing rolls of my attachment. y

With these ends in view my invention consists in the parts and combination of parts as will be more fully explained and pointed out in the claims. i

`.In the.accompanyingdrawings, Figure l is a view in front elevation of my improvement; Fig. 2 is a view in side elevation of rthe saine;` Fig. 8 is a view n'plan the cil cups being omitted; Fig. 4 is a view in longitudinal vertical section through Fig. 2:; Fig. 5 is a detached yview ofthe shaft caryrying` the upper roll as shown in full lines inFig. 1; Fig. 6 is a view in perspective of one of the bricksyFig. 7 is a view showing two bricks in their assembled position; Fig. 8 `is a view in perspective of the liner 5 Fig. 9 `is a View .in section similar to Fig. 4 showing a clay bar passing through the machine and a marker for the bar, and Fig. 10 is a view of the upper roller constructed as illustratedin dotted lines in Fig. 1.

l represents a die plate provided at suitable points with bolt holes for the passage of ythe bolts which secure the plate to the head Specification of Letters Patent.

' Application ined March 1s, 191e. serial No. 85,091.

of a brick making machine. This plate l is provided with an opening conforming in size and shape to the opening in the head of the brick machine, and is also provided with the forwardly or outwardly projecting integral side frames 2 and upper and lower projecting flanges 3 and 4. The sides 2 and flanges 3 and 4 are located at the four sides of the opening in the plate l, and sup port the lining 5 which is in. eect a die. The upper member of this lining is slightly inclined downwardly toward its outer end as 'shown in Fig. 9, so that the clay bar will be compressed and slightly reduced in depth as .it passes through the die. The liner may have slots as shown in the upper side where it comes in contact with roll 6, to permit of greater expansion of clay in the recesses or pockets in roll 6, for the formation of projections, and it may have ridges on top and bottom members, to assist rolls in producing longitudinal grooves in top and bottom of clay bar, which are finished by correspond ing ridges in top and'bottom roll. The said ridges produce grooves or troughs on the two sides 0f brick, so that when bricks are laid togetherthey form a recess for holding the grent, producing an interlocking bond which ksecurely holds the paving brick in position.

Located at the outer edge of the top member of the lining is the roll 6, the said lining being cut away and grooved as shown so as to permit the roll to lie close to the same and in a position to engage the clay bar as it leaves the top member of the lining, without any space between them into which the clay could pack, the said roll forming in effect a part of the die, as it imparts the finish to the upper face of the clay bar.

This'roll 6 is provided with a central enlargement 7 for forming a central grooveS longitudinally of the upper face of the brick 9,- and is also provided at each side of said enlargement with one or more recesses or pockets 10 into which the clay of the bar enters to `form corresponding projections 11 on the upper face of the brick.` This roll may extend slightly beyond the side of the die opening as shown at dotted lines 12 in Figs. l and 10, or of less width as in Fig. 5 and infull lines Fig. l, with its ends in close relation to the shoulders 13 formed on the upper member of the lining 5. With either of these constructions I am enabled to proiss vide for slightly rounded corners as at `14, thus producing similarly rounded corners on the brick.

The roll 6 may be integral with or secured to the shaft 15 by keys or otherwise, and is mounted in anti-friction bearings carried by the blocks 16. The blocks 16 are mounted at the upper ends of the side members 2, as shown in Fig. 2, and are secured thereto by the bolts 18, which are screwed into threaded openings formed in the upper ends of the side members 2. Each bolt 18 has a shoulder 19 thereon at the upper end of the threaded portion, which shoulders rest in pockets formed in the lower edges of the blocks 16, h-ence by turning the bolt, the blocks carrying the roll 6 can be adjusted vertically so as to accurately locate and adjust the roll 6 with relation to the front end of the die. These bolts 18 pass upwardly through the blocks 16 and secure them to the side frames and in proper relative position.

Mounted in ball bearings at the lower ends of the sides 2 and secured therein by the half bearings 19, is the shaft 20 carrying the lower roll 21, which as shown in Fig. 1 is preferably as long as the die is wide so as to completely support the clay block as itl emerges from the die. The roll 21 rests in a pla-ne slightly in advance of the roll 6 as clearly shown in Fig. 2, and beyond the outer end of the lining 5, o-f the die, so that Athe clay bar, as it vemerges from the die will be wholly supported by said lower roll and rotate it in the direction of movement of the clay bar.

This roll 21 is provided with a central enlargement 22 for engaging and finishing the groove 23 on the lower face of the brick 9, which enlargement may have thereon marks, such as the trade-mark, or namey of the brick, the name of the maker, etc., which marks or letters either sunken or raised, will of .course assist the weight of the clay bar in turning the roll 21.

, Secured to shaft 20 is the .pinion 23 which meshes with a smaller pinion 24: secured to shaft 15 carrying roll 6, so that the rotation of the roll 21 will rotate the roll 6. From this it will be seen that the outward move.- mvent of the clay bar rotates the rolls. Hence the movement of the latter always conforms to the speed of movement of the bar as it emerges from the machine.

lSecured to the tops of the blocks 16, and in front of the roll 6, is the plate 24a, recessed on its top to receive the wiper holder 25. This holder is recessed on its under face to receive the felt or other wiper 26 the free edge of which bears against the periphery of the roll 6 and operates to keep the latter free of any adhering particles of clay. This wiper may carry oil or other lubricant for lubricating the roll so as to lessen the tendping onto the lower roll, I employ the drain f 28 in the bottom of the eXtension, so located as to discharge the dripping in a plane to the rear of the lower roll. This is an 1mportant factor in preventing slippage of theclay column on the bottom roll.

This improvement is designed to be attached'to any stiff mud brick machine, and the rolls thereof are positively actuated by the passage of the clay or mud bar throughy the die. The rolls are not pressure rolls in the sense that they or yeither is forced by spring or oth erwise against the clay bar, nor is the upper roll so located that it acts on a surface of the bar fully shaped by the die, but on the contrary it is so located with relation to the die, and at a point where the clay being forced through, is under pressure so that the recesses in said upper roll will be filled by thepressure forcing the clay outwardly and not wholly by the expansion of the clay after it has been shaped.

The lugs or projections 11 on the bricks are preferably curved as shown and are so located that each brick or block formed will have avplurality of projections on one side, which as before explained operate to hold the bricks or blocks sufficient distance'apart while being laid to permit cement, grout or other filler to be readily poured or inserted between the bricks, and to keep them in alinement.

In Fig. 9 I have shown a frame 29'secured to the plate, 24a by the screws 18 and carrying a roller 30 which turns'freely on the axle 31 secured to the frame 29, the said roller having raised letters thereon for impressing a kword or name in the upper groove 32 of the clay bar. f

It is evident that many slight changes might be resorted to in thc relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to conne myself to the exact construction shown and described, but i Y Having fully described'my invention what I claim as new and desireto secure byl Letters-Patent, is V 1. lIn an attachment for a brick machine, the combination of a frame having. a die opening and flanges at the four sides thereof,

,a removable four sided integral die or lining within said opening and supported by the flanges, the top member of said die being icc out away at its outer end, the out away edge being shaped to conform to the periphery of a roll, a roll carried byy the frame and located adjacent "the free edge oit' the bottom of the die and in a position to receive the clay bar and be rotated thereby, and a roll mounted in saidfframe adjacent the "free edge of the top of the die with its lower portion resting in the said cut away and recessed portion of the die, whereby the lower portion oi the roll forms a continuation of the upper side of the die.

2. In an attachment for brick making machines, the combination of a frame having a box like opening, a lremovable four sided integral die or lining for said opening, the top member of said die being cut away and recessed at its outer edge and provided with a longitudinal ridge on its lower face, a roll carried by the irame and located adjacent the free edge of the bottom of the die in a position to receive the clay bar and be rotated thereby, the said roll being provided with a peripheral enlargement conforming to the ridge on the die, a roll adjnstably mounted in the cut away and re cessed portion ofthe die, and gearing con necting the two rolls whereby they will be rotated in unisonby the movement of the clay bar as it is ejected from the machine.

In an attachment for brick making mae chines, the combination of a die, a positively driven roll located to engage the top face of the clay bar as it is forced from the machine, a holder movably mounted with relation to said roll, means for moving and for locking said holder in place, and a wiper carried by the holder and engaging the periphery of said roller.

4L. In an attachment for brick making machines, the combination of a die, a positively driven roll located to `engage the top face of the clay bar as it is forced from the niachine7 the said roll having a plurality of recesses or pockets in its periphery and a peripheral enlargement, a flexible wiper and lubricator engaging the periphery of said roll, a holder for said wiper, and means for moving the holder toward the roll and adjustably secured to said frame.

5. In an attachment for brick making machines, the combination of a die, a roll located to receive the weight of the clay bar as the latter is forced from the die, a roll located to engage the top face of the clay bar and mounted in bearings which are adjustable toward and from the clay bar, the said latter roll having a plurality of recesses or pockets in its periphery, gearing connecting said rolls whereby they will be positively rotated by the movement oi' the clay bar, and an adjustable holder carrying a flexible wiper engaging the periphery of the top roll.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
